Evolution Racewerks Charge Pipe Kit — N55 (535i / 640i, X5 / X6)
Evolution Racewerks charge pipe kit for the N55 in the 5 and 6 Series and the X5/X6. The factory charge pipe on these cars is plastic and is a known boost-pressure failure point. This is its mandrel-bent aluminum replacement.
What it is
Mandrel-bent 6061 aluminum sized to the intercooler at 2.5", with a CNC-machined factory-style O-ring lock flange, beaded ends, T-bolt clamps, and silicone hose. Direct bolt-on using the factory routing.
Finishes
Brush, Polish, or Type III hard-anodized black — choose above.
Charge pipe vs lower-intercooler pipe
This is the main charge-pipe kit. On the X5/X6 there is also a separate Lower-Intercooler (LIC) pipe that replaces the cold-side run after the intercooler — pair the two for fully hard-piped charge routing.
Fitment
BMW N55 — 535i (F10), 640i (F06), and X5 35i / X6 35i (F15/F16). Confirm your chassis in the selector.
